As will be described in detail later, the shoulder portion 43 is a portion that engages with the claw 27 provided on the mounting portion 24.
Since the nozzle body 10A is a separate component from the below-described closing unit 20, when the nozzle body 10A is manufactured by injection molding or the like, resin can be supplied to various portions of a mold in a short time, and molding can be performed in a short time. Further, since the nozzle body 10A of the pouring nozzle 10 and the closing unit 20 are independent of each other, resin can be supplied to various parts of the mold, and a high-quality nozzle body 10A can be manufactured.
< closure Unit >
The closing means 20 is a structure for closing or opening the flow path 18 formed in the nozzle body 10A. The closing unit 20 is composed of a closing member 21, a mounting portion 24, and a connecting member 23.
(closure Member)
The closing member 21 is configured to be able to open and close the flow path 18 of the nozzle body 10A. The closing member 21 is formed in the same shape or substantially the same shape as the shape of the inner peripheral portion of the flow path 18, and is fitted into the inside of the flow path 18, specifically, the groove, to close the flow path 18. As shown in fig. 2 and 3, the intermediate portion in the thickness direction of the outer peripheral portion of the closing member 21 projects radially outward from one surface side (the other end portion B side) and the other surface side (the one end portion a side), and is easily engaged with the groove formed in the flow path 18. As described above, the groove is formed in the inner periphery of the flow path 18, and the outer periphery of the closing member 21 engages with the groove of the flow path 18, whereby the closing member 21 closes the flow path 18. On the other hand, when an external force is applied to the closing member 21 closing the flow path 18 from one surface side (the other end B side) to the other surface side (the one end a side), the outer peripheral portion of the closing member 21 is detached from the groove of the flow path 18. At this time, since the outer peripheral portion of the closing member 21 is formed in a tapered shape that becomes narrower toward the outer tip of the refill container 1, the closing member 21 is smoothly detached from the groove. As a result of the outer peripheral portion being detached from the groove, the closing member 21 is detached from the flow path 18, and the flow path 18 is opened.
The first projection 22 is formed on the other surface side (one end a side) of the closing member 21. Specifically, the 1 st projection 22 is provided on the other surface side (one end a side) of the closing member 21 at a position diagonal to the mounting portion 24. The 1 st projection 22 is a structural part provided as needed. In manufacturing the pouring nozzle 10, as will be described later, the 1 st projection 22 is used when the closing unit 20 is supplied to the nozzle body 10A.
(mounting part)
The attachment portion 24 is a structural portion for attaching the closing unit 20 to the nozzle body 10A. As shown in the upper part of fig. 2, the mounting portion 24 is composed of: a main body portion 25; 1 pair of arm portions 26 extending downward from the main body portion 25; and a 2 nd projecting portion 29 projecting upward of the main body portion 25. The 2 nd protrusion 29 is similar to the 1 st protrusion 22, and the 2 nd protrusion 29 is used when the closing unit 20 is supplied to the nozzle body 10A when the pouring nozzle 10 is manufactured.
Slits 30, 31, 32 are formed in the body 25. The slits 30, 31, and 32 are constituted by a linear slit 30 extending in the vertical direction of the mounting portion 24, an inclined slit 31 formed obliquely toward the closing member 21 side below the linear slit 30, and a vertical slit 32 formed between the arm portions 26. A bent portion 35 is formed at a portion corresponding to the inclined slit 31, the inclined slit 31 is inclined with respect to the linear slit 30 at the position of the bent portion 35, and the root side of the arm portion 26 is offset toward the closing member. The tip of the inclined slit 31 extends to the lower end of the main body 25. On the other hand, a coupling member connecting portion 28 protruding toward the closing member 21 is formed on the outer peripheral portion of the body portion 25. The connecting member connecting portion 28 is integrally connected to the connecting member 23. The base portions of the pair of arm portions 26 are provided at the lower end portion of the main body portion 25 with a predetermined interval therebetween by sandwiching the inclined slit 31 therebetween. The pair of arm portions 26 extends downward from the main body portion 25 with an interval equal to the groove width of the inclined slit 31. A portion formed between the arm portions 26 at the same interval as the groove width of the inclined slit 31 is a vertical slit 32. The claws 27 are provided at the distal ends of the arm portions 26 in the pair 1, and the claws 27 project toward the opposite side from the arm portions 26 as starting points. Each claw 27 is formed in a tapered shape so that the distal end side of the arm portion 26 becomes thinner.
(connecting member)
The connecting member 23 is a structural part connecting the closing member 21 and the mounting part 24, and is in the form of a string or a belt. When the closing unit 20 is manufactured by injection molding, the coupling member 23 is integrally molded with the closing member 21 and the mounting portion 24. At this time, one end of the connecting member 23 is connected to one surface side (the other end B side) of the closing member 21 opposite to the other surface side (the one end a side) facing the inside of the refill container 1. The other end of the connecting member 23 is connected to the mounting portion 24 of the connecting member 23 of the mounting portion 24. However, the closing member 21 and the attachment portion 24 may be formed separately from each other, and one end may be attached to the closing member 21 and the other end may be attached to the attachment portion 24.
The connecting member 23 includes a 1 st component 23a and a 2 nd component 23 b. The 1 st structural part 23a extends from the connecting member connecting part 41 toward the closing member 21, and the 2 nd structural part 23b is bent with respect to the 1 st structural part 23a and extends from the tip of the 1 st structural part 23a toward the 1 st surface.
[ configuration in which the closure member is opened ]
Fig. 5 shows an opened state of the closing member 21. In the state where the closing member 21 is opened, the attachment portion 24 side of the closing member 21 is supported by the mouth 58. Specifically, a portion of the 2 nd surface opposite to the 1 st surface of the closing member 21 corresponding to a portion where the coupling member 23 is coupled to the closing member 21 is supported by the coupling member 23. The supported region is a fixed region corresponding to a portion connected to the closing member 21. In the opened state of the closing member 21, the closing member 21 is held in a state in which the angle formed by the end face of the bonded portion 15 on the bag body portion 5 side is less than 90 degrees.
The coupling member 23 is limited to a certain length. Specifically, the length of the coupling member 23 is set within a range in which the 2 nd surface can be brought into contact with the outer peripheral surface of the nozzle 58. Such a coupling member 23 has a biasing force applied to the closing member 21 toward the mouth 58 side. That is, when the closing member 21 is opened, the coupling member 23 biases the closing member 21 in a direction to close the closing member 21 against the force of opening the closing member 21. As a result, the closing member 21 is sandwiched between the mouth 58 and the coupling member 23, and the closing member 21 maintains a stable open state.
Examples of the structure for applying a biasing force to the coupling member 23 include the following structures. That is, the coupling member connecting portion 28 is formed in the 2 nd protrusion 29. The coupling member connecting portion 28 is formed on the 2 nd projecting portion 29 of the mounting portion 24. Specifically, the coupling member connecting portion 28 is formed to protrude from the 2 nd protrusion 29 toward the closing member 21 side. One end of the connecting member 23 in the longitudinal direction is connected to the connecting member connecting portion 28, and the other end is connected to the 1 st surface of the closing member 21.
The refilling container 1 described above is used for filling the contents into the packaging container 50 described below. The structure of the packing container 50 is briefly described.
[ packaging Container ]
The packaging container 50 is a container to which the contents stored in the refill container 1 are replenished. The packaging container 50 is made of, for example, resin. Fig. 6 shows an example of the packaging container 50. The packaging container 50 shown in fig. 6 is constituted by a container main body 51 provided with a handle 52, and a pouring unit 55 for pouring out the contents stored in the container main body 51. When the contents transferred from the refilling container 1 are needed, the packaging container 50 is used by pouring a necessary amount from the packaging container 50.
The pouring unit 55 of the packaging container 50 is constituted by a main body portion 56 and a lid 59 for opening and closing the main body portion 56. As shown in fig. 7, the main body portion 56 includes: a peripheral wall surface 57; and a nozzle 58 disposed inside the peripheral wall surface 57. The peripheral wall surface 57 is cylindrical and has a hollow inside.
The nozzle 58 is disposed at the center or substantially the center of the body portion 56. The nozzle 58 is connected to the peripheral wall surface 57 and is formed integrally with the peripheral wall surface 57. The nozzle 58 projects upward of the body 56, and has a tip end located above the upper end of the peripheral wall 57. However, fig. 7 shows 1 example of the shape of the nozzle 58, and the shape of the nozzle 58 is not particularly limited.
[ step of replenishing the content of the refill container to the packaging container and action of the pouring nozzle ]
With reference to fig. 8, a procedure of replenishing the packaging container 50 with the content stored in the refilling container 1 and an operation of the pouring nozzle 10 of the present embodiment will be described. In fig. 8, the bag body portion 5 of the refill container 1 and the container body 51 of the packaging container 50 are not shown in order to facilitate understanding of the function of the pouring unit 55. However, the pouring nozzle 10 is attached to the refill container 1 shown in fig. 1, and the pouring unit 55 is attached to the packaging container 50 shown in fig. 8.
First, the lid 6 is removed from the pouring nozzle 10, and the refill container 1 is turned upside down so that the pouring nozzle 10 is positioned below the refill container 1. Since the flow path 18 of the pouring nozzle 10 is closed by the closing member 21, the content stored in the refill container 1 does not overflow. In addition, the pouring unit 55 of the packaging container 50 is previously detached from the body portion 56 by the lid 59.
Next, as shown in fig. 8 (a), the position of the pouring nozzle 10 is aligned with the position of the pouring unit 55 of the packaging container 50, and the refill container 1 is pushed down so that the nozzle 58 of the pouring unit 55 is inserted into the flow path 18 of the pouring nozzle 10.
When the refill container 1 is pressed down, the tip of the spout 58 pushes up the closure member 21. Therefore, as shown in fig. 8 (B), the blocking member 21 is detached from the flow path 18. That is, the outer peripheral portion of the closing member 21 is detached from the groove formed in the inner peripheral surface of the flow path 18 by an external force applied from one surface side (the other end portion B side) in the direction L extending from the flow path 18.
As shown in fig. 8 (B), in the state where the closing member 21 is opened, the attachment portion 24 side of the closing member 21 is supported by the tip end and the vicinity of the tip end of the nozzle 58. The length of the connecting member 23 is set within a range in which the 2 nd surface of the closing member 21 can be brought into contact with the outer peripheral surface of the nozzle 58 in a state in which the flow path 18 is open. Therefore, the mounting portion 24 side of the closing member 21 can be prevented from moving closer to the bag main body portion 5 side than the tip end of the spout 58, and a state in which the closing member 21 is not supported by the spout 58 can be avoided. In the state where the closing member 21 is opened, the closing member 21 and the end surface of the attached portion 15 on the bag body portion side are held in a state where the angle formed therebetween is smaller than 90 degrees.
The closing member 21 is biased toward the nozzle 58 by the connecting member 23. The connecting member 23 includes a 1 st structure portion 23a extending from the connecting member connecting portion 28 toward the closing member 21, and a 2 nd structure portion 23b bent with respect to the 1 st structure portion 23a and extending from a tip of the 1 st structure portion 23a toward the 1 st surface. The 2 nd projecting portion 29 is formed on the attached portion 40, and the connecting member connecting portion 28 projecting toward the closing member 21 side is formed on the 2 nd projecting portion 29. One end of the connecting member 23 in the longitudinal direction is connected to the connecting member connecting portion 28, and the other end is connected to the 1 st surface of the closing member 21.
Since the coupling member 23 and the coupling member connecting portion 28 are configured as described above, the coupling member connecting portion 28 applies a biasing force to the bent coupling member 23 to press the open-form closing member 21 against the nozzle 58. Therefore, as shown in fig. 8 (B), the closing member 21 maintains the open state.
